BOX-FASTENER.

SPECIFICATION forming part. of Letters Patent No.313,857, dated March 17, 1885.

Application tiled January 5, 18%. (No model.)

To @ZZ whom it may concern:

Be it known that I, SOLA B. DUNN, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a new and useful Improvement in Boxes, of which the following is a specification.

This invention relates to that class of boxes which are closed by sliding covers-such, for instance. as are commonly employed to hold watercolor paints, checker or alphabet blocks. ln this class of boxes,which are not very strong or perfectly made as a rule, there is great liability of the cover slipping out and the contents beinglost; and my invention is designed to remedy this evil, which I do by securing to the under side ofthe cover a flat metal spring provided with a shoulder adapted to engage with the end of t-he box when the cover is pushed into the closed position, said spring projecting to the outside of the box, so that it may be released when the cover isto be opened.

The drawings show at Figure l a plan of a sliding-cover box to which my improvement has been applied, and Fig. 2 is an end view thereof. Fig. 3 is a vertical sect-ion on line 3 3 of Fig. l, and Fig. 4 is a view similar to Fig. 3, showing the box partly open.

In said drawings, A represents the sliding cover of a box composed of ends B B', sides B2 B", and bottom B. The cover is fitted into grooves in the sides B2 B3 and end B in the ordinary manner of this class of packingboxes. arepresent-s a recess in the cover, designed to facilitate the sliding of the cover in opening.

C is a hat met-al spring attached to the under side of the cover by a rivet, c.. It is provided With a bend, c, which, when the cover is closed, engages with the end B of the box, as shown in Fig. 3. It also projects sufiiciently to the outside to enable the user to lift it out of such engagement when the cover is to be removed. The cover is recessed to permit the spring to be thus lifted, as shown at c. y This fastening can be applied to the boxes at a merely nominal cost, and the efficiency of the boxes is thereby very much increased, the contents being rendered secure. Ihe package may also be used without wrapping or tying when it is to be shipped by mail or express.

The spring may be secured to the under side of the cover in any convenient manner. In the drawings I have shown it secured bya rivet or small tack; but points or teeth may be eut in the edges or body of the spring itself and turned up so as to enter the wood, and` this latter is, perhaps, the better and cheaper construction. It is represented iii Fig. 5.

I claim- As a new manufacture, the box for toys, paints, Ste., closed by a sliding cover and provided with a shouldered spring secured to the under side .of the cover and adapted to en gage with the end ofthe box, the spring projecting to the outside, so it may be released, substantially as specified.
